Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment, it should be noted that accompanying drawing is only for exemplary illustration, can not be interpreted as the limitation of this patent; For those skilled in the art, some It is understandable that well-known structures and descriptions thereof may be omitted.

[0029] Such as Figure 1 to Figure 4 As shown, the free-form optical lens used for LED motorcycle headlights includes the optical lens 1 for the high beam light and the optical lens 2 for the low beam light in the same headlight, and the optical lens 2 for the high beam light. The lens 1 and the optical lens 2 for the low beam are convex-concave lenses, and the surface (11-1, 11-2) of the optical lens 1 for the high beam and the surface (21-1) of the optical lens 2 for the low beam are , 21-2) is the light incident surface, and the concave free-form surfaces (12, 22) of the two are light exi...

Abstract

The invention discloses a design method of a free-form surface integrated optical lens used for an LED (Light Emitting Diode) motorcycle headlamp. The lens comprises an optical lens used for a high beam and an optical lens used for a low beam in the same headlamp, wherein the optical lens used for the high beam and the optical lens used for the low beam independently consist of incident planes (convex surface and cylindrical surface), a side surface (side reflection surface) and an exit surface (concave free-form surface). The technical scheme provided by the invention is suitable for the new national standard of the motorcycle headlamp which uses the LED light resource, overcomes the problem that the current LED light source faces more complex optical design when the current LED light source is applied to the motorcycle headlamp, solves the defect of overhigh color temperature or low optical efficiency of the traditional motorcycle lens headlamp, and is convenient, reliable, mature and feasible.

Description

technical field [0001] The invention relates to the technical field of LED motorcycle lamp lighting, in particular to a design method of a free-form surface integrated optical lens for an LED motorcycle headlamp. Background technique [0002] With the continuous development of science and technology and the demand for complete vehicle configuration, there is a strong call in the automotive lighting industry to revise the requirements of GB5948-1998 "Light Distribution Performance of Motorcycle Incandescent Filament Light Source Headlamps". After the discussion and decision of the expert group, a mandatory national standard will be formulated. The name of the standard is tentatively designated as "light distribution performance of motor vehicle headlights emitting symmetrical low beam and / or high beam". After the standard is approved and issued, a transition period for implementation will be set , and gradually replace the current motorcycle headlight standard GB5948-1998 "li...
